RADIATOR- Application flled January 5, 1928. Serial No. 244,631.

This invention relates to an improvement in radiators for heating purposes, and has for its object to provide such a device which will, by reason of its peculiarities in design and construction, be particularly effective in performing the functions for which it is intended.

My improved radiator is so constructed that it may be used as a radiator of the built in type; that is, it may be located in a depression or recess in-the wall provided for it; or it may, if desired, be of the. conventional external type. Regardless of the manner in which it is used, its construction is such that it enhances the appearance of a room rather than detracts from such appearance, as is the case with most radiators in use at the present time.

In fact, the'present appearance of radiators now manufactured and in general use, and their tendency to collect dust, dirt and germs, and the difliculty in keeping such radiators clean and neat in appearance, has caused many persons to enclose'the radiators with ornamental metal casings or covers.

In some instances it is found that these supplemental casings thus applied tend to decrease the heating efliciency of the radiators considerably. Additionally, such radiator casings are expensive, the same in some instances costing more than the radiator on which-they are fitted.

My improved radiator presents the appearance of a radiator of the. covered type; it has smooth, flat and easily cleaned or painted outer surfaces; it has no project-' ing lugs, valves or parts requiring additional floor space; andfinally, it possesses as great, if not greater, heating efficiency as is found in any radiator of similar capacity in use at the present time.

- With these objects, and such other objects as may hereinafter appear, in view, I have devised the particular arrangement of parts hereinafter set forth and more particularly pointed out in the claims appended hereto.

Reference is to be had to the accompanying drawing, forming a part hereof, in which Figure 1 is a front elevation of my improved radiator;

. in construction and design.

Figure 2 is a side elevation of the same; Figure 3 is a plan view of the same;

Figure 4 is a vertical sectional view of the same on the line 44 of Figure 8, looking in the direction of the arrows;

Figure 5 is an elevation of the inside face of one of the end sections;

Figure 6 is a side view of one of the intermediate radiator sections;

Figure 10 is a sectional view on the line 10-10 of. Figures 5 and 6, looking in the direction of the arrows.

Throughout the various views of the drawings, similar reference characters designate similar parts. 1

Referring particularly to Figures 1 to 3 inclusive, it will be seen that my improved radiator consists of a series of separate sections adapted to be jointed or connected to form the assembled radiator. The size of the radiator and its capacity, is of course, dependent upon the number of these sections that are united. I The radiator is com osed of a pair of end sections 1 and 2, l ietween which are a plurality of connected intermediate sections 3, as many of these sections 3 being used as is required to produce the desired size of radiator.

The two end sections 1 and 2 are of similar construction with the exception of the fact that the faces of one of them are reversed with respect to the faces of the other, or in other words, one of these sections is made so that it properly fits the right end of the assembly while the other is made to fit the left end as will be clearly apparent from the drawings. These two sections are otherwise similar and thus'a description of one will suffice for the other. The intermediate sections 3 heretofore referred to, are all similar Referring now to the end section designated as 1 and more particularly disclosed in Figures 4 and 5. It will be here seen that the same consists of a substantially flat elongated hollow member having a flat outer side Wall or face 4 which extends downwardly and terminates at its lower end in a pair of spaced supporting legs 5. At 6 is shown the water or steam-containing chamber which is surrounded by the wall 4 and by a front wall 8, a back wall 7 and a top' Wall 39. The front wall8 terminates at somedistance from the top of the section 1, providing an outlet opening 49 for the passage of heated air as will be hereinafter described. It will be seen that at its upper termination, the wall or flange 8 is provided with an integrally formed-or cast inwardly projecting flange 9 which forms a battle plate for diverting the heated air ow. V

The water or steam chamber 6 just referred to, is made cellular by means of openings 10, which divide the chamber into a series of spaced water or steam passages or pipes 11, 12 and 13. Projecting outwardly from the face of the chamber 6 and integrally formed thereon, is a series of spaced inclined baflle plates 15, 16 and 17, these plates abutting against and co-operating with similar plates formed on adjacent radiator sections to cause air passing between adjacent sections of the radiator to follow a tortuous course and become heated while so doing.

At their upper ends the sections 1 and 2 are each provided with a boss 18, which, through the medium of a coupling nipple 19, connects these end sections 1 and 2 to a similar boss 20 formed on the adjacent intermediate radiator section 3. A closure plug 21 threads into and closes one side of the boss 18. At the lower end of the water or steam chamber 6, and at a point diagonally opposite to the boss 18, is provided a connection boss 23 which establishes a connection with a like boss 24 provided on the adjacent intermediate radiator section 3, a nipple 25 affording such connection. Through similar bosses 24 and like nipples 25 the various intermediate radiator sections may be readily connected as is disclosed in Figure 10.

At its extreme lower end, the chamber 6 has an opening or boss 26 which connects to an inlet pipe 27 having the customary shut-off valve 28. It will be seen that the pipe 27 is connected to the inner face of the section 1 and is located underneath the sections 3 in the space 60 provided between the legs of the end members 1 and 2. Thus said inlet pipe is so disposed that it is located within the plane of the radiator and thus requires no additional floor space. This is especially important where the radiator is to be used in a built-in construction, and it is also of considerable importance in other forms of construction since projecting inlet pipes and valves on radiators are more or less unsightly and apt to collect dust and dirt about them which is diflicult to remove. It will be noted also that the end radiator section 2 is provided with a boss 26 which receives an outlet pipe 29 that projects inwardly toward the inlet pipe and thence extends downwardly. The two pipes 27 and 29 are thus located Within the external dimensions of the radiator and therefore do not constitute additional projections therefrom or require additional space other than that occupied by the radiator itself.

Referring now to the intermediate radiator sections 3. As was heretofore stated, these are all similar in construction, so that a description of one will suflice for the others. Reference to Figures 6 and 7 of the drawings will make the construction of the intermediate sections clear. It will be there seen that each of said sections comprises a cellular water o-r steam-containing chamber 30 which is generally similar in shape to the chamber 6 found in the end sections 1 and 2. This chamber 30 thus has the openings 10 with the resultant passages or pipes 11, 12 and 13. Extending from the opposite faces of said chamber 30 are diagonal bafile plates 15, 16 and 17, these plates being so located that their edges meet and abut against the similar plates, 15, 16 and 17 provided on the end sections 1 and 2 or against similar plates on any adjacent intermediate section. It will be noted that in each of the intermediate sections 3, these baflle plates extend from both sides of the chamber 30 rather than from only one side as is the case with the end sections 1 and 2.

The chamber 30 in the intermediate sections, is surrounded at its back by a flange or wall 32 and at its top by an enclosing wall 33. At the front a similar wall 34 is provided, the upper end of this wall terminating at 35 where it is provided with an inwardly extending flange 9 similar in all respects and co-operating with the flange 9 on the end section 1. The lower end of the chamber 30 is open and not enclosed by any surrounding wall or flange, thus permitting a free and unrestricted upward sweep of air between the radiator sections, this air flow being caused to follow a tortuous course between the sections by means of the baffle plates there disposed. This causes the cool air which enters through the space below the radiator sections to become heated by the time that it.

emerges from between the sections at the top and passes out through the upper opening 49 provided by the interruption of the front flanges or walls on the various sections.

To increase the air flow between the radiator sections, I find it desirable to taper the lower terminations of the various chambers 30, astis disclosed at 40, so that a desirable draft or flue effect is produced.

From the foregoing, the construction and general operation of my improved radiator will be readily understood. It will be seen that I have provided aseries of connected radiator sections, each of which has a cellular water or steam-containing chamber, which has its back, top, and a portion of its front surrounded by a flange that lies transverse to the plane of the chamber. Thus when the various sections are joined together, the edges of the flanges of the adjacent sections meet or abut and the front, top and back of the completed radiator present substantially flat or plane surfaces. This not only produces a radiator which presents the appearance of an encased type, butit provides smooth, even outer surfaces which can be kept clean and free from dust and dirt or which can be painted, decorated or otherwise ornamented as may be required.

It will be seen also that the end members 1 and 2 have a flat outer surface 4 so that the ends of the radiator as well as the top, back and front, are flat smooth andunbroken.

The intermediate sections 3 will also be seen to be shorter than the end sections 1 and 2 so that when the various sections are joined together, the intermediate sections stand well above the floor, providing the space or opening 60 through which air may enter, the same passing upward between the various sections and following a tortuous course by reason of the bafile plates, until it emerges out through the opening 49 and thence into the room.

Having described one embodiment of my invention it is obvious that the same is not to be restricted thereto, but is broad enough to cover all structures coming within the scope of the annexed claims.

What I claim is 1. In a radiator adapted to be located in a wall depression, a radiator section having a hollow fluid-containing chamber, a flange faces across their back, front and top faces, the flanges on said sections being interrupted at the bottom and at the upper end of the front whereby an air channel is provided between the sections, said channel beginning at the exposed bottoms of the sections and terminating at the upper open front thereof, said assembly having its end sections extending below the intermediate sections, said end sections having inlet and outlet openings disposed toward one another whereby inlet and outlet pipes connected thereto will be located below the lower ends of the intermediate sections and between the end sections.

3. A radiator adapted to be located in a wall depression, said radiator being composed of a plurality of joined hollow sections, each of said sections havinga flange extending along its extreme edge, said flange being interrupted at the bottom of each section and again interrupted at the front of each section adjacent to'the top whereby a draft passage between the sections beginning at the bottom of the sections and terminating at the upper front part thereof is provided and connection openings being provided in said section, one of said openings being located adjacent to one end of the section near one of the longitudinal -edges thereof and the other opening being situated diagonally opposite adjacent the other end of the section.
